　　Here is the national weekend weather forecast from USA TODAY. I am Doyle Rice. (16) A remarkably quiet! calm weather pattern is on tap across the USA for the first full weekend of January. No extremely cold air or powerful winter storms are likely anywhere. There will just be some rain showers in the Southeast and light snow in the Rockies! and it will still be mild in the east. (17) Temperatures will continue to be quite mild across the country for early January. Above-average temperatures are expected for most of the nation! except for parts of the southern Rockies and in northern New England. Highs will rise into the 40s as far north as the northern Rockies and northern Plains, which is about 20 degrees above average. Only a few spots around the northern Great Lakes and northern New England will have temperatures below freezing Saturday and Sunday. Scattered showers are likely this weekend in the Deep South. By Sunday, the showers will also spread east into the Carolinas, and thunderstorms will be possible in the Gulf Coast. The rain is not forecast to be heavy enough to trigger any flooding. (18) Mostly light snow will fall in the central Rockies Saturday and the southern Rockies and western Plains Sunday. Little accumulation is expected, although a few inches are possible in the mountains of Utah, Colorado and New Mexico.
